Erlang The Movie (中文字幕)

A short Ericsson film demoing Erlang, showing concurrent processes, debugging tools, and hot code reloading, including crashing parts of a running system while calls continue.

Why HN likes it: A beloved classic that HN recommends as the quickest way to see why Erlang is special.

“the designers of Erlang demo some of the qualities of the Erlang system in a delightful way”
